Echo: sudo: security update to 1.9.16p2-3+deb13u2+e3

high Tenable Cloud Security Plugin ID 461158

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw was found in sudo. When sudoers rules use NOTBEFORE or NOTAFTER time-based access restrictions with
 timestamps that omit the trailing 'Z' timezone indicator, the time evaluation relies on the TZ environment
 variable inherited from the calling user. Because sudo is a setuid-root program, an unprivileged local
 user can set TZ to an extreme timezone offset to shift the authorization window by up to approximately 25
 hours, causing expired rules to be treated as valid. This allows the user to execute commands outside the
 intended time window. Authentication is not bypassed; only the time-based authorization check is affected.
 (CVE-2026-96512)

Solution

Update the sudo library and its related packages to version 1.9.16p2-3+deb13u2+e3 or later.
